Juli2301 [7.4K]

\frac{9}{56}\\ Fraction of hour was spent by NAncy in lifting weights

Step-by-step explanation:

Time spent at the gym by Nancy = \frac{7}{8}\,hour

Time spent at lifting weights =  \frac{5}{7}\,hour

What fraction of hour she spent in lifting weights?

Fraction of hour she spent in lifting weights= Time spend at the gym-Time spent at lifting weights

Fraction of hour she spent in lifting weights=\frac{7}{8}\,hour-\frac{5}{7}\,hour

=\frac{49}{56}-\frac{40}{56}\\=\frac{49-40}{56}\\=\frac{9}{56}\\

So, \frac{9}{56}\\ Fraction of hour was spent by Nancy in lifting weights

iragen [17]

Answer: 4 seeds will left over.

Step-by-step explanation:

Total sunflower seeds = 1354

Number of people shared sunflower  seeds equally = 6

By division operation,

Number of seeds each people will get = (Total sunflower  seeds) ÷ (Number of people shared seeds equally)

= (1354) \div (6)

=225\dfrac{4}{6}

Hence, each people will get 256 sunflower seeds and 4 seeds will left.

Write and equation for (-1,2) and (0,0)
Natali5045456 [20]
Since the slope is -2 because
x1: -1 x2: 0
y1: 2  y2: 0
y2-y1/x2-x1 = slope (0-2/0+1= -2/1 = -2)

You would havr to change it into point slope form so it would look like this
Y-2 = -2(x+1)
 y-2 = -2x -2
   +2          +2
y = -2x + 0
Hope this helps:)
